US state of Nevada lifts cannabis ban for athletes

The Nevada Athletic Commission has lifted a ban on athletes using cannabis, indicating it is not a performance enhancing substance. For the next 6 months, however, athletes competing in the state will continue to be tested for cannabis as part of an ongoing unrelated project. No penalties for use will be imposed.
